Animating a Material for only 1 Interval

I have an image material , i am animating it using panner node.

problem : i want to animate it only once , like when game starts , it starts animating once and stops .

any help regarding this is appreciated.

so , there is no way to achieve this using material editor ?

For this kind of effect, it is preferable to pass animation phase as a prameter from blueprint, instead of using Time material expression.

Exclusively in material -no. You would still need to pass either start time or end time to your material and later compare it with output of Time node.
